The circuit formed by transistors q1 and q2 is designed to turn on the red led pump protect whenever there is no water between pump protect electrode and ground electrode at pump reservoir.
Water tank level sensor circuit.

This is the circuit diagram of a simple corrosion free water level indicator for home and industries.
In the shown circuit the pin7 sensor will go to the tank full level or the brim of the sump tank pin1 will go to the full level or the brim of the oh tank.
When the sump tank is full it will switch on the motor when the oh tank is full it will switch off the motor.
Each transistor is switched on to drive the corresponding led when its base is supplied with current through the water through the electrode probes.
This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank.
The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components.
Q1 comes on as soon as water level drops below pump protect.
This device is capable of eliminating the manual method of checking water levels of the tanks at a regular time interval.
In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank.
The circuit is designed so that the buzzer will start beeping once the water tank is completely full.
The circuit is based on 5 transistor switches.
Ultrasonic liquid level sensor water tank liquid depth level meter sensor with temperature sensor water level gauge digital level measuring meter digital display.
In fact the level of any conductive non corrosive liquids can be measured using this circuit.
You can also use this device to sense the water level at a determined level.
Q1 base current is too small less than 1 micro amp.
